I have reciently set up a CentOS server to run Nagios and MRTG. Everything is working, but there is something strange going on. If I navigate to the Nagios page it webpage come up as expected. If I navigate to the MRTG page it acts like I am on dial up. I can watch each picture (graph) download. Not sure why there would be a difference.

I am new to linux and trying to learn. Can someone advise me where I can start to look around?

Well, when all else fails, start from scratch. I found the issue. The switch that it was connected did not like the auto neg for speed and duplex. So, I move the server into the server room and out of my office and everything is working like I think that it should. Thanks,

Also, is the MRTG routine calculating the data, creating the graphic and only then displaying it? If so, and if there is a lot of data, this could be an obviously slower process from the browser standpoint.
